FIELD: technological processes.
SUBSTANCE: method includes forming of permeable skeleton structure from contacting fibres and their integration into entity using thermal processing up to diffusive penetration. After that, working element is coated with layer of aluminium 5÷12 μm thick using magnetron sputtering in vacuum by flat magnetron with disbalanced magnetic field. At least 95% aluminium is used as a target. Before coating, the surface of working element is activated using ionic source. After the coating, the working element undergoes homogenising annealing, until aluminium penetrates into the surface of working element on at least 1.5 μm.
EFFECT: burner's working element lifetime significantly increases.
